Solar Calendar

Solar Calendar – the only perpetual calendar with zero error

The Solar Calendar is a unique, printable time system based on the Earth's orbit around the Sun. Unlike the Gregorian calendar – which has unequal months, an inaccurate zero year and growing error – this calendar offers an eternally correct rhythm for planning, work and family life.

What you get:

– 13 months × 28 days (each month identical, with 4 weeks)

– 1 or 2 unnumbered days (December 21 – the winter solstice, time for reflection)

– A clear table with all months and days, ready to print

– A visual diagram showing the cycle of the year and seasons

– Mathematical closure: zero error over 86,400 years (or 675 cycles of 128 years)

Bonus (inside the file):

– A clear explanation of the correction rules (every 4, 128 and 86,400 years)

– The real length of the tropical year (365d 5h 48m 45,97s)

– Information on why this calendar is 15 times more accurate than the Gregorian system

Details:

– Format: PDF (A4, printable)

– Language: English / Polish (you choose)

– Instant download – you can print it at home or in a copy shop

Suitable for: planners, self-organisers, families, schools, and anyone who wants to break free from the chaos of unequal months and fake holidays.
